DVD player. A DVD player is a device that plays discs produced under both the DVD-Video and DVD-Audio technical standards, two different and incompatible standards. Some manufacturers originally announced that DVD players would be available as early as the middle of 1996. These predictions were woefully optimistic.
To accomplish this task, when you actually place a DVD into a Blu-ray Disc player, the Blu-ray Disc player activates the red laser assembly so that it can read the DVD. In addition, when you place a CD into a Blu-ray Disc player, the same red laser assembly that is used to read DVDs is refocused to read the CD.
